Huawei’s TalkBand B1, unveiled at Mobile World Congress in Spain, is similar to most other smart bands worn around the wrist, keeping time and offering health-tracking features. But Huawei adds a little twist by making the device act as a Bluetooth headset for wireless phone calls.

Part of the wristband-like device comes off and turns into a earpiece, allowing users to make calls without taking their phones out of their pockets or bags. Huawei says the new device is compatible with both Android and Apple’s iOS operating systems.

The Shenzhen-based company, whose mainstay business is supplying telecommunications networking gear to carriers, is the latest company to enter the fledgling market for wearables. Ahead of the World Mobile Congress in Barcelona, Huawei, still little-known as a consumer brand, was teasing its first wearable device on Chinese social media sites.

Huawei says the TalkBand will become available in China next month, and then in Western Europe, the Middle East, Russia and Japan in the second quarter. In Europe, the suggested retail price is EUR99 ($136).

The price isn’t very low compared to more fitness-oriented smart bands. Nike’s FuelBand SE, for example, sells for $149 on the company’s online store.

Other than the wireless calling function, Huawei says the TalkBand’s podometer-like feature counts your steps and calculates how many calories you have burned. The company also claims that the device can keeps track of the duration and quality of your sleep.
